Soft-Resolution Method of Six-Element Linguistic Truth-Valued Intuitionistic Fuzzy Propositional Logic

摘要

In this paper,we construct a six-element intuitionistic linguistic truth-valued fuzzy propositional logic (6LTV-IP) based on the framework of linguistic truth-valued propositional logic,which can express both the comparable and incomparable truth values. Truth degree and falsity degree of intuitionistic fuzzy proposition are two truth values with linguistic hedge. With the concrete logic operation of 6LTV-IP,some special properties are obtained. Then based on (α,β)-complementary literals and (α,β)-similar literals,we propose a soft-resolution method of 6LTV-IP.
